Phase 3 electronic problem

The slide does not open when a coin drops on the copper elements. Connecting both elements with a little piece of wire: no action either. Touching one of the elements with my finger: slide opens! ????? how come ???? I loosened the small clamps from the copper elements. Touching a clamp with a coin: nothing happens, but scratching a coin with the clamp leads to opening the slide. What is happening?

When the Crow Box was brand new (1.5 years ago) the system was functioning flawless.

Anyone a brilliant idea or suggestion?

Inspired by the alternative wiring scheme of Rodion (see servo discussion startet on okt 19) I decided to use the other ground on the arduino. Coin sensor functioned…..only once. After that again as written above. After trying several weird options (for a weird problem you need weird solutions) I ended up with the following. Whole setup is according to original instructions, only the ground wire is loose. And it functions perfectly! Laws of phisics no longer apply I guess.

I hope they still don’t tomorrow, cause Jay is missing its peanuts and training sessions and I’m not going back to phase two.

Hi,

I think you have contact problems. Possibly poorly soldered or material problems. Can you send a photo of contacts for coins?

Very well possible. Interior has been wet/moist few times due to (unexpected) rain. Some corrosion is visible (on the little white electronic board) I might renew some parts coming weeks. But at this very moment the CrowBox functions well (90 pct of the coins are detected) despite the loose wire. I will keep you updated! Bye for now.

It's very good that everything works again.

Thanks all for jumping in on this; has anyone else had similar problems?
